Until Tuesday, North Korea appeared on Google Maps as a near-total
white space — no roads, no train lines, no parks and no restaurants. The
only thing labeled was the capital city, Pyongyang.

This all changed when Google, on Tuesday, rolled out a detailed map
of one of the world’s most secretive states. The new map labels
everything from Pyongyang’s subway stops to the country’s several
city-sized gulags, as well as its monuments, hotels, hospitals and
department stores.
